Dynamoelectric machine and stator

ABSTRACT

A dynamoelectric machine has a stator with a pair of opposite end faces and an interposed circumferential surface. Windings carried by the stator have a pair of annular groupings of end turns with outer circumferential portions arranged adjacent the opposite end turn portions of the stator, and a set of integral leads of the windings extend from one of the end turn groupings beyond a part of the outer circumferential portion. A terminal assembly is seated on the circumferential surface of the stator, and has a set of terminals with at least some of the terminals being connected in direct terminating engagement with the integral leads of the windings.

This application is a continuation-in-part of the commonly assignedapplication Ser. No. 496,552 filed May 20, 1983 and is related to thecommonly assigned application Ser. No. 496,524 filed May 30, 1983 witheach of such aforementioned applications being incorporated herein byreference.

FIELD OF THE INVENTION

This invention relates in general to electrical apparatus and inparticular to an improved dynamoelectric machine and an improved statortherefor.

BACKGROUND OF THE INVENTION

In the aforementioned application Ser. No. 496,524, split phase typemotors are disclosed utilizing a switch and terminal assembly supportedon an end frame of such motor and operated by a centrifugal device tocontrol the excitation of the auxiliary and main winding of such motor.The windings of the aforementioned split phase type motors were providedwith a set of integral leads extending from an end turn grouping of suchwindings and connected in direct terminating engagement with theterminals of the switch and terminal assembly mounted to an end frame ofsuch motor.

In past single or three phase type motors, many different schemes wereemployed to terminate the integral leads or lead ends of windings forsuch motors so that such integral leads could be connected with a powersource for exerting such windings to effect the energization of themotor. The aforementioned windings were, of course, magnet wireencapsulated within a suitable insulating material, and such magnet wirewas formed into a plurality of interconnected coils to comprise suchwindings. The coils had opposite side turns disposed in windingreceiving slots of a stator and opposite end turns which were formedinto generally annular groupings thereof adjacent the opposite end facesof the stator. Integral winding leads or lead ends on some of thewinding coils were brought out or exited from one of the opposite endturn groupings of such coils, and as previously mentioned, it was thennecessary to terminate such integral winding leads, i.e., electricallyconnect such integral winding leads, through some scheme or device whichcould conveniently be connected with a power source input power leads.

One of the most common past schemes for terminating the integral windingleads of motor windings in single or three phase motors was to merelycrimp, solder or otherwise connect input power leads or lead-inconductors with the integral winding leads of the motor windings. Theseinput power leads were respectively encapsulated within suitableinsulating means, such as a cloth-like insulating material or the like,for instance, and had a crimp-type fitting or quick connect type fittingon the free end thereof which could be connected with the input powerleads.

In another past terminating scheme, as shown in U.S. Pat. No. 4,004,169,crimping fittings were utilized to respectively interconnect theintegral winding leads of the motor windings with input power leads, andthe crimping fittings were then inserted into releasable engagementchannels or openings provided therefor in an insulating holder which wasmechanically mounted within the winding slots of the stator so as toextend from an end face thereof. One of the disadvantageous orundesirable features of this past terminating scheme is believed to bethe lack of any convenient means for grounding the stator of the motor.Another disadvantageous or undesirable feature of this terminatingscheme is believed to be that the crimping fittings might have beendisplaced from the channels in which they were received in theinsulating holder in response to handling of the motor or in response tomotor vibration effected uon the energization of the motor.

Another of the past terminating schemes, as shown in U.S. Pat. No.3,725,707, involved mounting an insulated holder or terminal blockagainst an end face of a stator between spaced apart end turn groupingsof the windings with parts of the terminal block being gripped betweensuch end turn groupings and stator end face thereby to retain theterminal block against displacement from the stator. Fittings werereceived in openings provided therefor the terminal block for releasablyreceiving input power leads inserted thereunto, and crimp-typeconnections were provided on such fittings exteriorly of such terminalblocks for interconnection with the integral winding leads of the motorwinding. One of the disadvantageous or undesirable features of this pastterminating scheme is believed to be that the terminal block might havebeen movable between the end turn groupings and stator end face inresponse to vibrations of the motor upon energization thereof and/ormovement of the end turn groupings of the windings upon the excitationthereof. If effected, it is also believed that the aforementionedundesirable movement of the terminal block might have resulted inmechanical working causing fatigue failure at the crimped connection ofthe fitting with the integral lead ends of the winding.

In U.S. Pat. No. 3,979,615, a connector housing or terminal block isfixedly mounted against a stator end face by a plurality of pins, andcontacts or fittings are removably insertable into openings providedtherefor in the terminal block so as to releasably grip or terminate theintegral winding leads of the motor winding and the input power leadsassociated therewith, respectively. At least one of the undesirable ordisadvantageous features of this terminating scheme is believed to bethat the fittings might have been dislodged from the openings in theterminal block so as to release or interrupt the termination of suchfittings between the integral lead ends of the windings and the inputpower leads.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the drawings, there is illustrated a method forassembling a stator 31 for use in a dynamoelectric machine 33 with aterminal assembly 35 (FIGS. 1-10). Terminal assembly 35 has a set ofterminals 37 with at least one electrical connector section or stud 39on at least some of the terminals (FIGS. 1-3). Stator 31 includes a pairof opposite end faces 41, 41a with a circumferential surface 43interposed, and winding or winding means 45 for the stator has a pair ofopposite generally annular groupings of end turns 47, 47a adjacent theopposite end faces of the stator with a set of integral winding leads orlead ends 49 of the winding extending from one of the opposite end turngroupings 47 (FIG. 1). In practicing this method, preselected ones ofintegral winding leads 49 of winding 45 extending from opposite end turngrouping 47 are interconnected in direct terminating engagement withpreselected ones of electrical connector sections 39 on terminals 37 ofterminal assembly 35, respectively (FIGS. 2-4). With the preselectedones of electrical connector sections 39 on terminals 37 in directterminating engagement with the preselected ones of integral windingleads 49 of winding 45, terminal assembly 35 is moved generally towardcircumferential surface 43 of stator 31 adjacent one of the opposite endfaces 41, and in response to such movement, and the integral windingleads of the windings are pivoted or generally rotated about theextension thereof from opposite end turn grouping 47 of the windings, soas to extend the integral winding leads across at least a part of theopposite end turn grouping generally radially outwardly thereof and in adirection generally toward opposite end face 41 of the stator (FIGS. 5and 6). Terminal assembly 35 is seated on circumferential surface 43 ofstator 31 at least adjacent opposite end face 41, and the terminalassembly is secured to the circumferential surface of the stator (FIG.6).

More particularly and with specific reference to FIGS. 1 and 2, terminalassembly 35 has a casing 51 with a plurality of interconnected wallmeans or sides 53, and the casing may be formed of any suitabledielectric material. Terminals 37 are mounted or otherwise supportedgenerally in row formation along a wall 53a of casing 51 with theelectrical connector sections 39 of the terminals extending exteriorlyof the casing beyond both wall 53a and another wall 53b of the casingadjacent wall 53a. Terminals 37 are also respectively provided withother electical connector sections 55 which are arranged to receive amultiple connector plug (not shown) which may be electrically associatedwith a power source and/or other electrical apparatus (not shown).Although terminals 37 are illustrated herein as having both electricalconnector sections 39, 55, it is contemplated that at least one of theterminals may have only one of the electrical connector sections withinthe scope of the invention so as to meet at least some of the objectsthereof.

Pairs of inner and outer circumferential portions 57, 57a and 59, 59aare provided on opposite end turn groupings 47, 47a in generallyradially spaced apart relation, and a pair of opposite free end portions61, 61a on the opposite end turn groupings extend generally between theinner and outer circumferential portions thereof, respectively. Oppositefree end portions 61, 61a of opposite end turn groupings 47, 47a arepredeterminately axially spaced from opposite end faces 41, 41a ofstator 31, and outer circumferential portions 59, 59a of the oppositeend turn groupings are predeterminately spaced radially inwardly ofcircumferential surface 43 of the stator. Integral winding leads 49 ofwinding 45 extend or are brought out of end turn grouping 47 in agrouped together or clustered relation generally at the same preselectedlocation or area on the end turn grouping so as to protrude beyond outercircumferential surface 59 thereof. Although integral winding leads 49of winding 45 are disclosed herein as exiting end turn grouping 47 atleast adjacent its free end portion 61 so as to extend beyond outercircumferential portion 59 of the end turn grouping, it is contemplatedthat the integral winding leads may be brought out at any convenientlocation on the end turn grouping between its free end portion andopposite end face 41 of stator 31 within the scope of the invention soas to meet at least some of the objects thereof.

With integral winding leads 49 of winding 45 extending beyond outercircumferential portion 59 of opposite end turn grouping 47, asdiscussed above, stator 31 and terminal assembly 35 may be located bysuitable fixturing (not shown) at a work station in preselected fixturedor located positions with respect to each other and with respect to acrimping device (not shown) having a set of crimping jaws or dies or thelike for instance as indicated at 63, 63a in FIG. 2. Since neither theaforementioned fixtures or the crimping device form a part of thisinvention, details thereof are omitted for the sake of brevity ofdisclosure and drawing simplification. When stator 31 and terminalassembly 35 are so arranged in the preselected fixtured positions asmentioned above, a set of free ends or end portions 65 on integralwinding leads 49 of winding 45 are predeterminately and convenientlydisposed or positioned generally adjacent terminals 37 of the technicalassembly. Thus, free ends 65 of preselected ones of integral windingleads 49 of winding 45 may be successively positioned at least adjacentpreselected ones of electrical connector sections 39 on terminal 37within or at least adjacent crimping jaws 63, 63a, and the crimping jawsmay be successively actuated in response to a crimping force appliedthereto, as indicated by force arrows Fc in FIG. 2, to crimp a crimpingsleeve or ferrule 67 about the free ends on preselected ones of theintegral winding leads of the winding and the electrical connectionsections of the terminals, respectively, as best seen in FIGS. 3 and 4.Of course, during this crimping operation, the crimping engagement ofcrimping sleeves 67 about free ends 65 on integral winding leads 49 andelectrical connection sections 39 on terminals 37 interconnect themagainst displacement in direct terminating engagement with each other,respectively. As discussed above, integral winding leads 49 andelectrical connector sections 39 on terminals 37 are successivelycrimped together, and to achieve such successive crimping, at least oneof crimping jaws 63, 63a, stator 31 and terminal assembly 35 in thepreselected fixtured positions thereof may be indexed. However, it iscontemplated that multiple crimping jaws or crimping jaws havingmultiple crimping recesses therein may be utilized to effect a generallysimultaneous crimping of at least some and perhaps all of free ends 65on integral winding leads 49 with electrical connector sections 39 onterminals 37 within the scope of the invention so as to meet at leastsome of the objects thereof. Futher, although free ends 65 of integralwinding leads 49 are illustrated herein as being bared or stripped,i.e., with the winding means electrical insulation material removedtherefrom, it is contemplated that crimping sleeves may be utilizedwhich cut through or sever such electrical insulation material so as toeffect the interconnection in direct terminating engagement between theintegral winding leads and the electrical connector sections of theterminals thereby to obviate the need for the aforementioned baring ofthe free ends on the integral winding leads within the scope of theinvention so as to meet at least some of the objects thereof. Instead ofthe above discussed crimping operation, it is also contemplated that theinterconnection in direct terminating engagement between free ends 65 ofintegral winding leads 49 and electrical connector sections 39 onterminal 37 may be achieved by other suitable means, such as forinstance soldering, brazing or welding or the like, within the scope ofthe invention so as to meet at least some of the objects thereof.Additionally, it is contemplated that either fewer or a greater numberof integral winding leads and terminals than those illustrated hereinfor purposes of disclosure may be employed within the scope of theinvention so as to meet at least some of the objects thereof.

Subsequent to the above discussed interconnection of integral windingleads 49 to terminals 37, stator 31 and terminal assembly 35 may beconjointly moved to another work station to effect the disposition ofthe terminal assembly in the seating relation thereof on circumferentialsurface 43 of the stator, as best seen in FIGS. 5 and 6. At this time,if desired, a device, such as a separator or insulator 69 or the likefor instance, formed of any suitable material having the desireddielectric properties and resilient characteristics, such as forinstance a resinous foam or the like, may be associated with theinterconnected integral winding leads 49 so as to both separate them andinsulate them from each other as well as opposite end turn grouping 47,as shown in FIGS. 1 and 5. A strip of tape 71 having suitable dielectricproperties is adhesively secured to insulator 69 to retain integralwinding leads 49 against displacement from a plurality of separatinggrooves 73 in the insulator for receiving the integral winding leads,respectively. Thus, when positioned in spaced relation adjacent outercircumferential portion 59 of opposite end turn grouping 47, insulator69 not only serves to electrically insulate between the end turngrouping and the integral winding leads but also serves to dampenvibration which may be imparted to the integral winding leads upon theexcitation of winding means 45 to effect energization of dynamoelectricmachine 33. While insulator 69 and tape 71 are illustrated herein forpurposes of disclosure, it is contemplated that such insulator and tapemay be omitted or that other insulators of different materials andconfigurations may be employed within the scope of the invention so asto meet at least some of the objects thereof. It is also contemplatedthat insulator 69 and tape 71 may be associated with integral windingleads 49 as previously mentioned after terminal assembly 35 is arrangedin the seating relation thereof on circumferential surface 43 of stator31, as discussed hereinafter.

As illustrated herein for purposes of disclosure, circumferentialsurface 43 of stator 31 has at least one flat side or flat portion 75thereon for seating engagement with terminal assembly 35; however, it iscontemplated that the circumferential surface of the stator may havevarious different configurations suitable to receive the terminalassembly in seating relation within the scope of the invention so as tomeet at least some of the objects thereof. To effect the seating ofterminal assembly 35 on flat portion 75 of stator circumferentialsurface 43, the terminal assembly and integral winding leads 49 areconjointly rotated or otherwise moved generally about the preselectedexiting location of the integral winding leads from end turn grouping 47with such rotation or movement being in a direction generally toward theintersection of end face 41 of the stator with the flat portion on thecircumferential surface of the stator, as best seen in FIG. 5. Thus,when another wall 53c opposite wall 53a on casing 51 of terminalassembly 35 is disposed in seating relation with flat portion 75 oncircumferential surface 43 of stator 31, as best seen in FIG. 6, it maybe noted that integral winding leads 49 extend generally in radiallyspaced relation beyond and across at least a part of outercircumferential portion 59 of end turn grouping 47. Further, althoughwall 53c of casing 51 is shown herein for purposes of disclosure asextending in part beyond opposite end face 41 of stator 31 so as to begenerally radially spaced from a part of end turn grouping 47, it iscontemplated that wall 53c of the casing may be seated in its entiretyon flat portion 75 on circumferential surface 43 of the stator. Prior tothe movement of terminal assembly 35 into the preselected positionthereof in seating relation with flat portion 75 on circumferentialsurface 43 of stator 31, a hardenable adhesive material 77 may beapplied onto at least one of wall 53c on casing 51 and the flat portionon the circumferential surface of the stator; therefore, upon curing thehardenable adhesive material to effect the hardening thereof, thehardenable adhesive material adheres between the casing wall and theflat portion thereby to secure the terminal assembly againstdisplacement from its position in seating relation with the flat portionon the circumferential surface of the stator.

Subsequent to the crimping of integral lead ends 49 of winding means 45into direct terminating engagement with electrical connector sections 39on terminal 37 of terminal assembly 35 and the securing of the terminalassembly in seating relation with flat portion 75 on circumferentialsurface 43 of stator 31, the stator may be moved into another workstation for assembly with other components of dynamoelectric machine 33,as best seen in FIGS. 1 and 7. The assembly of the components ofdynamoelectric machine 33 may be achieved by any suitable assemblyequipment or fixturing, but for the sake of brevity of disclosure anddrawing simplicity, a discussion of such assembly equipment andfixturing is omitted with the exception of a set of shims illustrated indotted outline at 79 in FIG. 7. Shims 79 may be interposed between arotor 81 of a rotatable assembly 83 and a bore 85 of stator 31 toestablish a suitable air gap therebetween as the rotatable assembly isdisposed in assembly relation with the stator. Thereafter, a pair ofsuitable lubrication and bearing systems, indicated generally at 87,87a, carried on a pair of opposite end frames 89, 89a may be received injournalling and lubricating association about a pair of opposite endportions 91, 91a on a shaft 93 of rotatable assembly 83 on which rotor81 is carried. If a more detailed discussion of lubrication and bearingsystems 87, 87a is desired, reference may be had to the commonlyassigned Charles W. Otto application Ser. No. 377,554 filed May 12, 1982(now U.S. Pat. No. 4,466,165 issued Aug. 21, 1984) which is incorporatedherein by reference. End frames 89, 89a may be moved along shaft endportions 91, 91a toward positions located in assembly relation with apair of sets of opposite abutment ends 95, 95a provided on a set ofbeams 97 associated or otherwise fixedly connected with stator 31 atleast generally adjacent circumferential surface 43 thereof, and it maybe noted that flat portion 75 on the circumferential surface is disposedbetween an adjacent pair of the beams. With end frames 89, 89a solocated in assembly relation with respect to opposite abutment ends 95,95a of beams 97, a set of through bolts 99 may be inserted through thebeams and also through a pair of sets of apertures 101, 101a providedtherefor in the end frames to maintain the end frames againstdisplacement from their location in assembly location with the oppositeabutment ends of the beams, respectively. Of course, a set of lock nuts103 or the like for instance may be threadedly received on through bolts99 in locking abutment against end frame 89a. With the above discussedcomponent parts of dynamoelectric machine 33 so interconnected orsecured together in their assembly relation or assembly positions, shimset 79 may be withdrawn through end frame 89 from the air gapestablishing or shimming position thereof between stator bore 85 androtor 81. Thus, while positioned in their assembly relation, end frames89, 89a, stator 31 and beams 97 are secured together againstdisplacement thereby to define a stationary assembly 105 ofdynamoelectric machine 33 whereby rotatable assembly 83 is rotatablewhile in its assembly relation or assembly position with respect tostationary assembly 105. Further, if a more detailed discussion of theconstruction stator 31 and beams 97 is desired, reference may be had toU.S. Pat. No. 3,867,654 issued Feb. 18, 1975 to Charles W. Otto which isalso incorporated herein by reference. Although rotatable assembly 83and stationary assembly 105 of dynamoelectric machine 23 are illustratedherein for purposes of disclosure, it is contemplated that various otherrotatable and stationary assemblies of different constructions andhaving component parts with different configurations associated witheach other in different manners may be utilized within the scope of theinvention so as to meet at least some of the objects thereof.

With reference again to the drawings in general and recapitulating atleast in part with respect to the foregoing, there is also illustratedanother method of assembling stator 31 for dynamoelectric machine 33with terminal assembly 35 therefor (FIGS. 10-12). Terminal assembly 35includes casing 51 with terminals 37 supported thereon, and stator 31includes opposite end faces 41, 41a with circumferential surface 43interposed (FIG. 1). Resilient means, such as a spring 109 or the likefor instance, includes a deformable intermediate section or portion 111interposed between a pair of opposite end portions 113, 115 dependingtherefrom, respectively (FIGS. 10-12). In practicing this method, casing51 of terminal assembly 35 is disposed or placed in a preselectedposition in seating relation with circumferential surface 43 of stator31 with terminals 37 spaced therefrom (FIG. 10). Intermediate section111 of spring 109 is arranged or positioned in overlaying relation withcasing 51, and a part of the intermediate section is engaged or seatedon the casing (FIG. 11). Opposite end portions 113, 115 of spring 109are associated or interconnected in releasable engagement withconfronting parts on stator 31 at least adjacent circumferential surface43 thereof, respectively, and thereby intermediate section 111 of thespring is deformed or deflected at least in part into facing relationwith casing 51 thereacross (FIG. 10). In response to the association ofopposite end portions 113, 115 of spring 109 with stator 31 and thedeformation of intermediate section 111 of the spring, the spring isstressed, and thereby casing 51 is biased or urged against displacementfrom its preselected position in seating relation with circumferentialsurface 43 of the stator (FIGS. 10 and 12).

More particularly and with specific reference to FIGS. 10-12, whenterminal assembly 36 is placed in its preselected position on stator 31,wall 53c on casing 51 of the terminal assembly is seated in abutmentwith flat portion 75 on circumferential surface 43 of the stator. Withterminal assembly 35 in its preselected position, intermediate section111 of spring 109 is positioned so as to extend generally across wall53c of casing 51 with a part of the intermediate section engaging wall53c. Thereafter, applied forces, as indicated by force arrows Fa in FIG.11, are exerted against spring 109 at least generally adjacent oppositedepending end portions 113, 115 thereof, and in response to the exertionof applied forces Fa, the depending opposite end portions are displacedinto gripping or releasable engagement with confronting parts ofadjacent ones of beams 97, respectively. It may be noted that oppositedepending end portions 113, 115 are provided with a pair of detents orhooks 117, 119 which effect the gripping or releasable engagement withbeams 97, respectively. The exertion of applied forces Fa onto oppositeends 113, 115 of spring 109 also serves to effect the deformation ofintermediate section 111 thereof. Thus, in response to this deformation,intermediate section 111 of spring 109 is biased into engagement withwall 53a on casing 51 of terminal assembly 35 thereby to urge wall 53copposite wall 53a of the casing into the seating relation thereof withflat portion 75 on circumferential surface 43 of stator 31. A pair ofparts or studs 116 on wall 53a of casing 51 are received in a pair ofopenings 118 provided through intermediate section 111 of spring 109thereby to comprise means for positioning engagement between the casingand the spring; however, it is contemplated that other positioningengagement means of various configurations may be utilized within thescope of the invention so as to meet at least some of the objectsthereof. Further, spring 109 is illustrated herein for purposes ofdisclosure generally in the form of a leaf type spring, it iscontemplated that other resilient means having various otherconfigurations may be employed within the scope of the invention so asto meet at least some of the objects thereof. It is also contemplatedthat crimping sleeves 67 may be crimped into engagement about integralwinding leads 49 of windings 45 and electrical connector sections 39 onterminals 37 of terminal assembly 35 thereby to effect theinterconnection in direct terminating engagement between the integralwinding leads and the electrical connector sections either before orafter the terminal assembly is secured to stator 31, as previouslydiscussed in detail hereinbefore. Thus, the association of spring 109,stator 31 and terminal assembly 35 provides an alternative constructionfor such stator and dynamoelectric machine 33 in one form of theinvention, respectively, meeting at least some of the objects thereof.

In an alternative construction in one form of the invention when spring109 is associated with stator 31 and terminal assembly 35, as discussedabove, terminal 121 of the set of terminals 37 on casing 51 of theterminal assembly comprises a ground terminal, as best seen in FIG. 13.Means, such as an extension or abutment 123 or the like for instance, isprovided for connection between intermediate section 111 of spring 109and ground terminal 121 thereby to associate or interconnect stator 31in ground circuit relation through the spring with the ground terminal.Extension or connecting means 123 has one end thereof secured bysuitable means, such as welds 125 or the like for instance, tointermediate section 111 of spring 109, and an opening 127 is providedin the other opposite end of the extension through which ground terminal121 protrudes. A pair of opposed flanges 129, 131 on extension 123adjacent opposite sides of opening 127 therein are arranged in abuttingor contacting engagement with ground terminal 123. While welds 125 areillustrated to secure extension 123 to spring 109 for purposes ofdisclosure, it is contemplated that other suitable means, such as tabsor the like for instance, may be employed to mechanically interconnectthe extension and the spring within the scope of the invention so as tomeet at least some of the objects thereof. It may be noted that spring109 not only serves as a means for retaining terminal assembly 35against displacement from its preselected position on circumferentialsurfaces 43 of stator 31 but also acts with extension 123 to connect thestator in ground circuit relation with ground terminal 121 of terminalassembly 35.

In another alternative construction in one form of the invention asshown in FIG. 14, a conductor or ground wire 133 has one end thereofcrimped by a crimping sleeve 67 into contacting engagement withelectrical connection section 39 on ground terminal 121 of terminalassembly 35, and the other opposite end of the ground wire is connectedby suitable means, such as soldering, brazing or welding or the like forinstance, with intermediate section 111 of spring 109. Thus, spring 109and ground wire 133 act to connect stator 31 in ground circuit relationwith ground terminal 121 of terminal assembly 35. It is, of course,contemplated that ground wire 133 could be connected by suitable means,such as quick connect fittings or welding or the like for instance, toeither spring 109 or electrical connector section 39 on ground terminal121 of terminal assembly 35.

In another alternative construction in one form of the invention asshown in FIG. 15, spring 109 is associated with stator 31 and terminalassembly 35 in the same manner as previously discussed; however, groundterminal 121 is omitted from terminal assembly 35a. In this alternativeconstruction, spring 109 includes an integral ground terminal 135 lancedor otherwise displaced therefrom so as to be disposed in a preselectedposition generally in the row formation along wall 53a on casing 51 ofterminal assembly 35. Thus, spring 109 not only defines a means forretaining terminal assembly 35 against displacement from the preselectedposition thereof in seating relation with flat portion 75 oncircumferential surface 43 of slots 31 but also provides integral groundterminal 135 in the row formation with terminals 37 on terminal assembly35a. It may also be noted that the interconnection of opposite endportions 113, 115 of spring 109 with stator 31 connects it in groundcircuit relation through the spring with integral ground terminal 135thereof. While integral ground terminal 135 on spring 109 is illustratedfor purposes of disclosure as being arranged in the row formation withterminals 37 of terminal assembly 35a, it is contemplated that theaforementioned preselected position of integral ground terminal 135 maybe displaced from the row formation of terminals 37 on terminal assembly35a within the scope of the invention so as to meet at least some of theobjects thereof.

In another alternative construction in one form of the invention asshown in FIG. 16, the above discussed spring 109 is replaced by ametallic strap 137 as a means for retaining terminal assembly 35 againstdisplacement from its preselected position seated on stator 31. In thisalternative construction, strap 137 includes an intermediate section 139arranged in overlaying facing relation or abutment with wall 53a oncasing 51 of terminal assembly 35, and a pair of opposite ends or endportions 141, 143 integral with the intermediate section on the strapand depending therefrom are secured to circumferential surface 43 ofstator 31 by suitable means, such as welds 145, for instance. Posts 116on wall 53a of casing 51 are received in positioning engagement througha pair of openings 149 in intermediate section 139 of strap 137 therebyto comprise a means for positioning engagement or abutment therebetween.While posts 116 are illustrated on casing wall 53a of terminal assembly35 as protruding through a pair of openings 149 provided therefor inintermediate section 139 of strap 137 to effect the aforementionedpositioning engagement between the strap and the terminal assembly, itis contemplated that other means may be utilized for effecting suchpositioning engagement between the strap and the terminal assemblywithin the scope of the invention so as to meet at least some of theobjects thereof. Albeit not shown for purposes of brevity of disclosureand drawing simplicity, it is also contemplated that the alternativeconstructions illustrated in FIGS. 13-15 with respect to spring 109 mayalso be utilized in the same manner in connection with strap 137 of FIG.16 to effect the ground circuit relation with stator 21 within the scopeof the invention so as to meet at least some of the objects thereof.Thus, strap 13 not only may be utilized as a means for retainingterminal assembly 35 against displacement from the preselected positionthereof on stator 31 but also may act to connect the stator in theground circuit relation as previously discussed hereinabove.

In still another alternative construction in one form of the inventionas shown in FIGS. 17 and 18, the above discussed spring 109 and strap137 are replaced by a spring clip 151 and a ground terminal 153 arrangedin predetermined spaced apart relation and fixedly secured by suitablemeans, such as welds 155 or the like for instance, onto flat portion 75on circumferential surface 43 of stator 31. The above discussed groundterminal 121 is also omitted from an alternative casing 51a of terminalassembly 35. In this alternative construction, a casing 51a of aterminal assembly 35a is provided with means, such as a slot 157 or thelike for instance, intersecting with walls 53a, 53c of casing 51a forreceiving ground terminal 153, and means, such as a notch 59 or the likefor instance, is provided in casing 51a for receiving in releasableengagement a free end or detent 161 on spring slip 151. When terminalassembly 35a is placed in its preselected position on stator 31, groundterminal 153 extends through slot 157 in casing 51a into the rowformation with terminals 37 along wall 53a of the casing, and detent 161of spring clip 151 is disposed in notch 159 of the casing. Groundterminal 153 is provided with opposite extending means, such as forinstance serrations or barbs 163 or the like, for interfering ordisplacement preventing engagement with casing 51a of terminal assembly35 when the ground terminal is received in slot 157 thereof. In thismanner, it may be noted that spring clip 151 and ground terminal 53serve as means for retaining terminal assembly 35 against displacementfrom its preselected position in seating relation with flat portion 75on circumferential surface 43 of stator 31, and it may also be notedthat ground terminal 153 is connected directly to stator 31 in groundcircuit relation therewith. While spring clip 151, ground terminal 53,and casing 51a of terminal assembly 35 are illustrated herein forpurposes of disclosure, it is contemplated that other spring clips,ground terminals and casings having various other configurations andassociated with each other in various different manners may be employedwithin the scope of the invention so as to meet at least some of theobjects thereof.

In yet another alternative construction in one form of the invention asshown in FIGS. 19 and 20, a spring 109a has generally the same componentparts as previously discussed spring 109 with the exception that aspring clip 151a and a ground terminal 153a are lanced or otherwiseformed from intermediate section 111 of spring 109a so as to extendtherefrom and openings 118 are omitted from intermediate section 111 ofspring 109a. In this alternative construction when spring 109a isassociated in assembly relation or position with stator 31, hooks 117,119 on depending end portions 113, 115 of spring 109a are arranged ingripping or releasable engagement with beams 97 on stator 31 in the samemanner as previously discussed, and intermediate section 111 of spring109a is disposed in overlaying relation or engagement with at least apart of flat portion 75 on circumferential surface 43 of stator 31. Uponthe association of spring 109a in assembly relation with stator 31,spring clip 151a and ground terminal 153a extend from intermediatesection 111 of the spring in a direction generally away from flatportion 75 on circumferential surface 43 of the stator so as to receivecasing 51a of terminal assembly 35a. When terminal assembly 35a isplaced in its preseleted position on stator 31, it may be noted thatwall 53c of casing 51a is seated at least in part against intermediatesection 111 of spring 109a, and ground terminal 153a on the springextends through slot 157 in casing 51a into row formation with terminals37 along wall 53a of the casing while detent 161 on spring clip 151a ofthe spring is disposed in notch 159 of the casing. Thus, barbs 163 onground terminal 153a are disposed in interfering or displacementpreventing engagement with casing 51a of terminal assembly 35a when theground terminal is received in slot 157 thereof, and spring clip 151a isarranged in displacement preventing engagement with the casing. In thismanner, it may be noted that terminal assembly 35a is carried onintermediate section 111 of spring 109a so as to be located thereby in apreselected position on flat portion 75 of circumferential surface 43 ofstator 31, and it may also be noted that spring clip 151a and groundterminal 153a on spring 109a, respectively, serve as means for retainingterminal assembly 35a against displacement from its preselectedposition.
